What Our Clients Say

Testimonials

Paul was friendly and was able to easily diagnose our electrical issue. He even sat down to explain a range of repair options.
Emily Fedler
Great job! Explained everything. Awesome. Suggested a water filtration system to reduce sediment.

Over the course of my experience with NH Ross, I have invested thousands of dollars in their services. Unfortunately, the journey has been marked by repeated issues and considerable frustration. After the installation of two new central air conditioning and heating units, I encountered numerous problems that required multiple service callbacks. While the technicians typically addressed these concerns, a persistent refrigerant leak remained unresolved. Each spring, I was forced to recharge the system due to this leak. Despite visiting my home on at least two occasions to locate the source and charge me for a sealant process, NH Ross was unable to identify it. Instead, they proposed a costly solution—installing new copper tubing along the exterior of my home—without confirming that the piping was the actual issue. I continued to spend thousands of dollars maintaining the system, yet NH Ross declined to perform a pressure test, which could have pinpointed the problem. Eventually, I engaged a different HVAC company to conduct a pressure test. Within seven minutes of their service call, they identified the leak at the connection point between the copper tubing and the A/C unit. They repaired the connection, pressurized the system with air, and monitored it over several days to ensure there were no further leaks. The system has since been operating properly. I am deeply dissatisfied with the service provided by NH Ross. I communicated the steps I was going to taking to resolve the issue and was assured that a manager would contact me to assist. That call never came.

He did a very professional job rebuilding the faulty toilet. In addition he took the time to see that it was working properly before leaving.

Explained step by step what he had to do and took pictures of everything he did a wonderful job, Left area completely clean. Thanks Paul
Nat Lacov
The plumbers were at the top of their game. They were professional and carefully explained the options provided with the services they provided. Although the project last as longer than expected these guys worked until they believed the job was perfected. Long day but I truly appreciated the job they did. Great job guys.
